Research contributions
Cumulant expansions in geophysical flows
Marston developed applications of cumulant expansion techniques to study turbulence and statistical equilibria in atmospheric and oceanic systems. Key contributions include:
- Barotropic jet dynamics: demonstrated that second-order cumulant expansions (CE2) accurately reproduce statistics of unstable jets on rotating spheres for weakly nonlinear regimes.[1]
- General circulation modeling: extended CE2 to a two-layer baroclinic model, showing agreement with direct numerical simulations (DNS) for statistically steady states.[2]
- Atmospheric applications: co-authored work applying cumulant expansions to parameterize eddy-mean flow interactions in atmospheric models.[3]
Interdisciplinary innovations
Marston's work intersects quantum physics and climate science:
- Proposed using quantum computing to simulate classical nonlinear systems, including atmospheric dynamics.[4]
- Analyzed albedo changes from large-scale carbon dioxide removal strategies, highlighting unintended climate impacts.[5]
